What is the ruling on opening a grocery store in a remote neighborhood without a license from the government?

The basic principle regarding trade in permissible goods is permissibility. However, this may be overridden by circumstances that render it impermissible, such as a ruler's prohibition of engaging in it without permission or a license, in order to regulate people's affairs and monitor goods, thereby achieving a benefit or averting harm. For the ruler has the right to restrict the permissible for a recognized public interest. However, if the interest in the restriction is not apparent or is private, there is no harm in disobeying it, as long as it does not lead to self-abasement or exposure to punishment.
